Yes I've noticed it was quite a "special feature" when saw it printed on the catalogue. It supposedly helps with mpg by closing when possible to redirect air better... If this appearance mod of mine goes forward I may remove the shroud and shutters completely. Is there any electronic items that'll be affected? Fuse, warning lights, etc?

I realize the coolness part of it and I absolutely enjoy this car with this feature. But I'll be (trying) to do somewhat extensive custom mod to front end and the shroud and shutters may not look good so we'll see haha.

Did you buy a jug of coolant from the dealership to top it back off? What specific blend of the oem motorcraft coolant should I request? There was 2 different ones cited in the thread. About to do mine after new years since my extended warranty will officially be up.

There's only one correct coolant for the MK3 Focus (either in concentrate, or premixed), and it's the VC-3-B Motorcraft Specialty Orange coolant (for concentrate), or VC-3Dil-B for the 50/50 premixed variety of Motorcraft Specialty Orange coolant.

Out of ALL the modifications I've done to my car this has been by FAR the worst to do! Still going at the bottom bolt on the thermostat housing. Probably going on two hours or more now.
I take that back, the spring/shock swap was the worst but this was a close second.

Edit* Done now. ETA should read 4 hours and 50 minutes instead of the previously quoted 45 minutes lol. Instead of the open wrench on the bottom bolt you can save a lot of time by squeezing in the long 1/4 inch extension in there. Wish I would've known. I also did not get the temp gauge read out on the test screen. It was my first time using it but I got a bunch of blank colored screens.

Edit* test mode can be achieved by having key in accessory mode and holding down ok/right arrow on LEFT of the steering wheel. While holding for 5 seconds turn key from accessory position to run position. After another 5 seconds or so of holding the test mode will appear on display above steering wheel.

Say what you will but at least the next guy has an appropriate outlook on the time range he's looking at. Could be 45 minutes to 4 hours depending on mechanical ability. I gave an honest start to finish estimate. I'm not a mechanic by trade, nor do I work on cars every day. However, I do pride myself in doing all the work myself. My eibach sportlines/ST struts and shocks took me 7 hours to install. Is that the quoted estimate in the books? No, but it gives the slow average joe guy like myself a more real world estimate. 90% of guys are faster than me but I know my work is spot on and I don't cut corners.

Torretto!

Some guy claimed that one guy with hand tools and no lift could do a full spring swap in one hour or two at the most..I called BS on him as I myself have done this in about 4 cars and only the ones that I had pulled all that apart several times and was very familiar could I do it in less then 2 hours.

Sounds like this would be a good thing to do, at the same time as I do the intake manifold..pull manifold off, install thermostat and then go to town on the intake manifold, yee haw!!

I just did mine yesterday. It took about 2-1/2 hours and the worst part was getting the upper hose off after one of the ears broke off of the hose clamp. I ended up cutting it off with a die grinder but a Dremel would have worked as well or better I just don't have one. I didn't have any trouble getting the lower bolt out, the trick was using the short and medium 1/4" wobble extensions I bought ages ago from Harbor Freight. Also, definitely take out the headlight. It takes about two minutes and provides more room. The clip was a bit different, you pull the tab back towards the leads instead of push down like most connectors. If I had to do it again (and the other clamp doesn't break) I think it would take 1 to 1-1/2 hours.

If you don't have wobble extensions or swivels buy them, they are worth the $15 in time saved and you have them for future projects.

I've always been the type to have pride in the fact that I do my own work. And with that sometimes comes a better product. I knew I wanted an intake on my new Focus. I wanted a K&N filter. And I wanted it to be functional without being too "ricey", or have too much over-powering intake noise. So...

Decided to do a quick write up on how to reaplce your rear motor mount in a n/a mk3. Bare with me as im not one for words, give me a break im a motorcycle mechanic, so this thread uses a lot of pictures.
To get started you are going to need a T30 torx bit, 13/15mm wrenches or sockets, a lift...

Hey guys, pretty new here and looking to get into the focus modding game. Love my car, it's a 2.0L N/A 2012 focus mk3 sedan. Here in Australia it's called the trend, which is equivalent to the SE for you Americans I think? Either way, just want to know if the
K&N Air Filter Assembly - KN57S4000...
